UNIT'ED STATES PATENT] QFF Original application filed September 13, 1923, Serial No. 662,528. Divided and this application m December 7, 1925.

This is a divisional application divided out of applicants patent a plication' for ept. 13, 1923,

is detach'ably secured to a tractor orother vehicle or engine, so that it may be secured or detached by the application or removal of a few bolts, whereby the entire device may be readily moved over the entire field to be harvested and ginned and whereby when the picking and ginning is completed,

the vehicle may be free for other work.

This invention relates more specifically to a vacuum cotton harvester and gin,the vacuum being produced by a positive acting rotary pump. I

Among the objects of my device are included the fabrication of a machine having a plurality of hoses and nozzles for picking and a plurality of vacuum tanks, removable,

collapsible cotton containers being detach-' ably secured in the tanks in sliding engagement. A further object is "to provide each of the tanks with'adust screen by which air is thoroughly screened of all dust and trash entering the vacuum pump. The'bags are provided with a scam in which are formed eyes which may be positioned on hooks formed on a pipe, which in turn is positioned in sliding engagement in a second pipe positioned at the inner top of the container. By this means the bags may be easily inserted and removed. Furthermore the bags are made sufiiciently porous to permit any fine dirt that may be associated with the cottonto sift through to the vacuum tanks from which it maybe easily removed. Simplemethods of securing the;

open ends'of the bags in the vacuum tanks 7 are provided so'that the bags maybe quickly attached. Means for deflecting the cotton lengthwise in the sacks are also included.

With these and other'objects in View my tures of construction and arrangement of parts as will be hereinafter more fully described,'pointed out in the claims, and illustrated in the drawings, in which, i

sacks, together with its retaining ring.

Fig. 3 is a fragmental, longitudinal, secf tional elevation of a sack rod and guide.

Fig. 4 is a transverse, sectional elevation on. the line.4.4r of Fig. 3..

Numeral 5 designates one of'a plurality of vacuum tanks consisting of the shell, suchasG open at the front end and having fiangesi, and the door, such as 8 hingedly secured to the flange with the fiat spring. door catch '9 attached to hold the door A rubbergasket is inserted in the flange to seal the door. In the doors are formed glazedopenings in order to make the interior of the tanks visible. A vacuum pressure gage such as 10 is placed'on the shell (5.111 a convenient positlon. 'By the means of thepipe 11 and the valve 12, and

the pipe'13, the tank 5 is placed in fluid shown). I h

The entry or the cotton to the tank 5 is made through the-curved spout 14 which is inserted into the pipe. .15 which passes through the shell 6, as shown in Fig. 1.

communication with a vacuum pump (not A metallic dirt screen box 16 held together by the bolts '17 is secured in the rear endof the tank 5. A porous cloth is tied over the screen box 16 in order to further screen the dirt and prevent. it passing from the tanks to the pump. The cotton upon enterin the tanks is deposited in cloth sacks 18 o the length but smaller in diameter than the tanks. The air is permitted to circulate between: the sack and tank, as best shown in Figs. 1 and 2.

Thespout 14 has its free endin a horizontal planeso that the cotton is shot longitudinally into the sacks. The cloth sack 18 is open at one'end.= In 'orderto' maintain the receiving end of thesack 18 at an open and not in a collapsible position, the ring l9.is employed. Theend' of the sack'18 is stretched over the ring 19, leaving the sack end open. The sacks are then tied to the ring bymeans of the cord 20. In order to hold the sacks in thetank in an open position, the following instrumentalities are employed. A longitudinal seam such as 21 60 tudinal, sectional elevation of one of my Y is formed on each sack, having eyes 22 formed therein at regular intervals. A pipe 28, having a longitudinal slot formed therein is positioned at the top of the insideof the vacuum tank and secured to the front and rear thereof. A pipe 24;, having a handle 25 and hooks 26 secured thereto at various points is placed in sliding engagement in the pipe 23 so that the hooks 26 will slide through the slots 27. The hooks 26 are spaced apart the same distance as arethe eyes 22. The bags may, therefore, be suspended in the tanks by hanging them on the hooks 26 by means of their eyes 22. To insert or remove a bag in or out of its tank, the curved} spent 14 is removed and the pipe 24 simply slid in or out of the pipe 23,

What I claim and mean to secure by Letters Patent is,

1. An elongatedcontainer positioned with its longitudinal axis in a horizontal plane and containing a sack which is so suspended therein as to retain its extended position, and with its opening at one end to receive the cotton. v

2. In a cotton harvester, an elongated sealed container having a detachable cover at one end and a suction connection at the other, a fixed member disposed longitudinally within said tank adjacent to the wall thereof, a sack open at one end for receiving the cotton, means engageable with said member for detachably supporting said sack within said container in spaced relation therewith so as to form an annular air space between said sack and said container, a cotton delivering hose centering said container near the open end of said sack, and a discharge spout in said container and connected to said hose, said spout having its discharge end presented longitudinally of said sack toward the open end thereof for discharging the cotton toward the closed end of said sack.

3. In a cotton harvester, an elongated sealed container arranged in a horizontal plane and having a detachble cover at one end and a suction connection at the other, a member fixed longitudinally within said container adjacent to theivall thereof, a sack having one end open for receiving cotton,means for slidably engaging said rnemher and detachably supporting said sack in said container in spaced relation therewith to provide an annular air space between said sack and said container, and a cotton delivering spout extending into said tank I and having its discharge end presented within the open end of said sack for discharging cotton longitudinally into said sack.

4. In a cotton harvester, an elongated container arranged in a horizontal plane having an open end adapted to be hermetically closed, a suction connection leading from the opposite end of said container, a sack of sieve material, said sack being of smaller dimensions than the inside cimensions of saidcontainer, means for detachably sup porting said sack throughout its entire length in a horizontal plane within said container in spaced relation therewith, and a cotton delivering spout disposed within said container with its discharge mouth presented toward the open end'of said sack and having exterior connections for delivering cotton into said'sack.
